Product Overview
The HTR-20D three-roll mill achieves grinding and dispersion through the mutual compression of three horizontal ceramic rollers and the shear forces generated by different rotational directions and speed differences, making it an effective grinding and dispersion equipment for high-viscosity materials. With a processing capacity ranging from a minimum of 0.02 L/hour to a maximum of 20 L/hour, it reliably bridges the gap between laboratory testing and small to medium-scale trial production. Its highly innovative design makes the equipment more compact and space-efficient, allowing it to be conveniently placed on a laboratory table. The gap is adjusted using an interactive touch screen, offering higher stability, with real-time display of gap and pressure values, making operation easier and more precise. The pressure curve function assists in real-time analysis of the dispersion process and status.
Product Features
1. The ceramic roller is made of zirconia ceramic powder, offering excellent dimensional stability, resistance to deformation, no black spots, stain resistance, easy cleaning, and abrasion resistance.
2. The dual-bearing structure effectively eliminates the influence of bearing clearance, vibration, and other factors, improving grinding precision and equipment stability.
3. The one-button zero-position calibration function enables automatic recalibration to the zero position when gap deviation occurs or when the roller is heated or cooled.
4. Equipped with a human-machine interface and a vertical multi-color touchscreen that responds quickly, with vivid colors and high saturation.
5. It adopts multi-point closed-loop drive, equiangular linear amplification mechanism, parameterized adjustment, precise gap adjustment algorithm, convenient operation, stable gap, and adjustment accuracy of 1 μm.
6. The discharge blade holder is made of aluminum alloy, with a special hard anodized surface treatment for corrosion resistance and scratch resistance. The self-adaptive balanced blade holder structure ensures better fit.
7. The ceramic roller protective cover is made of plexiglass to prevent foreign objects from falling into the equipment when idle.
8. Leveling adjustment feet facilitate easy leveling, ensuring stable operation on various platform environments and improving grinding performance.
9. Stainless steel material tray: prevents material from falling onto the machine body and causing corrosion.
10. Cleaning safety bracket: prevents cleaning tools from falling into the feed roller and damaging it during equipment cleaning.
11. Emergency stop: emergency stop button.
12. The base is cast from aluminum alloy, and the side panels are made of aviation-grade aluminum alloy plates. All materials undergo long-term, repeated stress-relief processes before machining, ensuring excellent structural strength, high precision, and dimensional stability.
Working principle
The HTR-20D three-roll mill achieves grinding and dispersion through the mutual compression of three horizontal ceramic roller surfaces and the shear force generated by different rotational directions and speed differentials. This equipment ensures precision and stability in the grinding process through multi-point closed-loop drive and equiangular linear amplification mechanisms, utilizing parameterized gap adjustments.
Application Areas
High-viscosity material grinding and dispersion, laboratory testing, and small-to-medium scale trial production.
Steps of Operation
1. Gap Mode: The roller gap is set via the touchscreen, and the gap recipes used can store at least 10 groups, each with at least 10 segments.
2. Pressure Mode: Operates under a set roller pressure, with a maximum roller pressure of ≥ 200 N/cm.
3. Compensation Mode: If a gap deviation occurs, it can be adjusted online through the touchscreen, allowing the user to make corrections.
4. Cleaning Mode: Gap, pressure, and rotational speed automatically adjust to a safe range for convenient cleaning.
5. Roller Gap Zero-Position Self-Calibration Function: Periodically and automatically calibrates the roller gap to ensure long-term stable operation.
6. Operation Interface: In gap mode, the roller pressure curve is displayed.
7. Supports multi-level operation permission settings on the interface.
8. Includes safety alarm functions with prompts and recovery operations.
Precautions
- Before operation, ensure the equipment is placed stably and adjust it using the leveling feet.
- When cleaning, use the cleaning safety bracket to prevent cleaning tools from falling into the feed rollers and damaging them.
- Note the location of the emergency stop button for immediate shutdown.
- Prevent foreign objects from falling into the equipment; use the ceramic roller protective cover when idle.
- Pay attention to the safety alarm function prompts and perform recovery operations promptly.
- Multi-level operation permission settings should be followed according to specified permissions.
